我們在九十一年十一月開始準備做科學實驗，利用 學校的筆記型電腦和麥克風開始做聲音錄音測試實驗，使用的軟體是在家庭錄音室網站（網址：http://club.ntu.edu.tw/~NTUMCS/studio.htm）下載的 Gold Wave 軟體，發覺這是一個可以試試看的聲音實驗。於是我們在 九十一年十一月測試，十二月初開始做實驗，並於九十二年四月底完成實驗，整個實驗歷時約半年，做實驗時間是利用禮拜六的早上。利用九十一年五月，這一個月整理數據，寫研究報告。第一個實驗是利用一支高感度麥克風（離原點 90~40 為公尺），和一支小麥克風（置於原點）來接收同一槍聲，我們利用兩支麥克風的距離除於電腦錄音程式上兩支麥克風槍聲的時間間隔，即為聲速。接下來，我們做短距離聲音的隔音實驗，將警報器置於紙箱同一位置並固定，紙箱包覆不同的材質，改變包覆材質的層數，並改變紙箱距小麥克風距離（小麥克風處為原點，接上電腦），比較隔音效果，並探討不同箱子大小，是否影響聲音振幅。第三個實驗是利用較長距離的收音（約 40 公尺），利用一把雨傘，將大麥克風綁在雨傘的中央收音，改變雨傘張開角度，看是否影響聲音振幅大小，另外我們也做了一個類似雨傘模型，貼上珍珠板，測試是否影響聲音振幅大小。

The purpose of the research is to investigate the settling mode of the viscid micro-particle, such as the ones from the “Miso Soup”, in static liquid. We constructed the “constant temperature environment” by constant temperature trough and transparent glass trough. The data is gathered from pictures captured from DV and then analyzed by Media Player. We did a stability test prior to the start of the experiment and found the system with good stability. The results of the experiment are as followed: 1. The settling mode can be divided into four phases: (a) Initial accelerated phase (b) Maximum phase (c) Gradually decelerated phase (d) Stationary phase. 2. The lower the fluid concentration is in the fixed temperature: a. the faster its settling interfaces appears; and the deeper it becomes for the depth of its settling interface. b. the faster the maximum sedimentation rates of the settling interface becomes and the slower it appears. 3. At the fixed concentration, the higher temperature: a. has the bigger maximum sedimentation rates of the settling interface b. gets to the stationary phase sooner c. has shallower stationary settling interfaces d. the time when the settling interface appears is independent with the temperature 4. The shape of the container has no effect on the settling mode as the settling interface is always perpendicular to gravity field. 5. If we add salt into the liquid, the stationary settling interfaces of the result will be higher than non-added ones.本研究的目的在於探討味噌這樣的微小黏性顆粒，在靜止液體中的沈澱模式。運用恆溫槽與透明玻璃水槽所建構之恆溫環境透過數位攝影機，以電腦播放軟體於特定時間擷取畫面進行分析。在正式實驗前，進行了穩定性試驗，發現穩定性良好。實驗的結果發現：一、 沈降模式：可以分為四個時期，分別為（一）起始加速期（二）高峰期（三）逐漸穩定期（四）完全靜止期。二、 在固定溫度下，溶液濃度越低：(一) 出現沈降交界面的時間越短且穩定距離距液面越深。(二) 沈降面沈降速率最大值越大且出現的越晚。三、 在固定濃度下，溶液溫度越高：(一) 沈降面沈降速率最大值越大。(二) 沈降交界面完全靜止期出現的時間越短，也就是越快達到穩定。(三) 沈降交界面的穩定距離距液面越淺。(四) 沈降面沈降速率最大值出現的時間與溶液的溫度無關。四、 容器內部的形狀與沈降面的沈降行為並沒有影響，都是成與重力場垂直的水平線沈降。五、 添加食鹽之後最終穩定沈降面比同濃度同溫度的高了許多。表示添加了食鹽對於味噌溶液有阻止沈澱的效果。

Purpose of the research I had a bicycle accident eight months ago and I suffered an opened humeral fracture. I wasn’t able to get up on my feet, I had to suffer on the ground while a couple accidentally walked there, and they called the emergency services, I lost a lot of blood and the doctors had to cut a small piece of muscle out of my biceps. Now this shouldn’t have happened if there were a faster method on making first aid. Example an intelligent flying robot could easily handle this situation. Procedures There is a hexcopter and a quadcopter. Both of them has cameras with live image transmissions in Full HD and they also have GPS. They are equipped with a lot of sensors (image recognition with Raspberry Pi, 6 axis distance sensors, long range communication modules) and with these they are able to solve problems just a bird or a human does. These drones can communicate up to 1.8 kilometers, they communicate with the main server, they share their knowledge with each other and this way they can learn about the world and about the terrain that surrounds them. In a very basic way they are able to learn… Each time they make their flying techniques smoother and their database is growing. These drones can cooperate and save lives faster than humans do. They are also able to fly in non-accessible zones by themselves with no human help. For example with their sensors they can fly in and map buildings that are inaccessible for people. They can also do artificial farming with their object recognizing features, like recognizing plants and colors. (Right now they are calibrated to look for survivors alone in the mountains/forests.) They go to a given GPS coordinate then they are flying in a spiral form to find the injured people in less than a half hour. I really hope that one day these flying intelligent machines will save lives! Note: (I probably can only take one drone with myself to Taiwan, because of the traveling restrictions on planes.)

本研究希望在數位顯示方面做些改進，利用電腦運算使戶外大型LED看板所使用之能源降到最低，以達到節能減碳。\r 本研究分為兩個部份:\r 第ㄧ部份:以瑞利準則探討亮點間距與觀賞距離之關係。\r 實驗中，以Photoshop繪圖模仿LED燈泡之排列，分析兩亮點之大小、距離與觀測距離的關係來設定點之尺寸，再進一步分析三原色點之觀測距離、比例及三原色點之佈點方式對混色效果之關係，並以瑞利準則判斷之。\r 得到公式如下：\r 自己所繪之點大小/點恰可分辨之最近距離=LED燈之間隔/點恰可分辨之最近距離=0.8mm/1m \r 第二部份:數位顯示—LED。\r 利用第一部份所得知的公式發現：在某ㄧ觀賞距離時，有最佳的影像品質且有最少的用電量。較近時，則影像品質降低；而較遠時，影像品質已無法提昇，而多餘的用電量則可經由實驗省去。藉由本次實驗結果，可利用所編寫之程式計算出在某ㄧ距離下最適合之燈泡尺寸及所省之電量，以達到節能減碳的效果。

本研究整合了碎形圖形的迭代運算方法與基因交配觀念來達到音樂創新，並透過音樂和諧性判別機制來提高創新音樂的悅耳程度。利用基因觀念之交配的方法來解決長短的問題。這個方法是把原始音符輸入後，找出它們的中心點，以這個中心點為準，其他的音符按照一定比例向外延展，成為新的迭代點。再利用這些迭代點，迭代出新的音符。把製造好的音符染色體放置到交配池中，以隨機的方式在交配池中選取其中之一個染色體進行交配的動作，此二音符染色體會交換彼此的基因，產生下一代新的代表音符長短之染色體，隨後以「模仿母體判斷式」來判斷這新一代的音樂是否與母體音樂相似，藉此淘汰掉「不肖的」下一代，而若新一代與母體的相似程度高的話，它的悅耳性相信也會相對提高。最後把這些技術應用於數位音樂創作，以衍生新穎應用與創新的結果。Fractals can be produced by IFS (Iterated Function Systems). By iterative computation of many times, we can obtain the similar graphics. In my research, the methods to generate the iterative algorithms were presented. In addition, I would discuss the regularity and the content as well as the properties of those digital patterns. At last, the advanced application of fractals to digital music pieces was presented. The program took a note of several measure of music as the beginning point, and made the IFS calculations for each new note in each measure. But there was no difference in beats if you just make the IFS iteration. So I changed the beats with genetic crossover method. In this research, the expression of the DNA to each beat of note was adopted. The same way, it took a note as a beginning point. And the system obtained the new DNA from the old notes for new ones randomly. After producing the new pieces of music, I want to know if it is good to listen. So I used the algorithm that checks the simulation to the shape of mother music. If its shape is similar to the mother music, the probability that the new music is pleasing may even increase. That would make a piece of brand new music. What I want to do in this research is improve the multiformity of music and find what the relationship is of ‘good music’ and mathematical algorithms

在練習作電腦動畫的過程中，做出以電腦模擬自由落體及雙星運動，但以上都屬可簡單分析出結果的運動，因此想到以電腦模型預知無法簡單分析的問題。在牛頓雜誌第 1 69 期，有一篇文章曾提到拉格朗日點：假設宇宙中有三個星體，星體 A （太陽）質量甚大於星體 B （本星），而 B 質量遠大於星體 C 。當 C 位於五個稱為拉格朗日點的位置上時（如圖），會與 B 的角速度一致，環繞 A 公轉。圖中L1L2L3三點處於極不安定的平衡位置，而位在L4L5的小行星群即使因撞擊而略為離開拉格朗日點，由於 A ， B 引力的微妙作用，仍會回到穩定的點上。我們就是對這情形感到興趣。 \r

Whe we think of chemistry experiments in schools from the view of environmental\r protection, microscopic chemistry experiment with reduced quantity and waste is\r the trend for experiments in the future. It is also the target that everybody shall\r aim for. After many failures and instructions from teachers, I finally successfully\r performed electrolysis of the most micro-volume of one-drop solution. It was also\r unbelievable to perform quantitative test within the electrolysis time of color\r disappear from the blue cupic sulfate solution. \r To clearly see the one-drop solution electrolysis, instrument starts from magnifier\r to self-assembled micro project, then upgraded to the miro-visual screen. It not\r only can record,also plays/shows in the computer. Most importantly, it is the most\r environmental protection effective and also zero pollution microsopic chemistry\r experiment. It is obviously a target of future development trend. \r 我們從環境保護的角度去思考常校的化學實驗時，減量減廢的微型化學實驗已是未來實驗的趨勢，也是大家應共同努力的目標。在多次失敗及老師的啟發下，我終於成功的做到電解最微量的一滴溶液。對於從藍色硫酸銅溶液顏色消失的電解時間裡，還可做定量的檢定感到不可思議！ \r 為了更清楚看到一滴溶液的電解情形，儀器的設計由放大鏡到自組顯微投影機，最後進階到顯微視訊的畫面，它不但可記錄下來，而且可在電腦中播放。最重要的是：最環保也最接近零污染的顯微化學實驗，已然是未來可發展下去的目標。

我們先假設有一正方體及一截過正方體之平面，並設正立方體為一k*k*k 之立體。為計算平面截過之單位正立方體個數，我們必須先分別計算各層被切過之個數再將之相加，因此將各層面投影至同一平面，簡化為平面上之問題，並討論其性質／規律，計算平面截此正立方體之個數。如此，便可以一般化數學式計算平面截正立方體個數之問題。接著，用以上方法為基礎，討論各種平面切正立方體之類型，將被平面所截之單位立方體個數以電腦程式算出，觀察數字變化及其性質規則，並找出最大值發生之條件。 We initially supposed that there are a regular hexahedron consists of unitary n × n cubes and a plane which incises the regular hexahedron. To calculate the total number of the unitary cubes incised by the plane, we can first calculate them layer by layer and then sum them up. And further, we project each layer on the same plane, so the three-dimensional problem is simplified into two-dimension. By making use of the character which results from projection, we can easily calculate the number of the unitary cubes incised. Consequently, we are able to calculate them with a general equation. Afterward, we research each circumstance that the plane incises the regular hexahedron on the base of the mentioned methods. Calculate them with self-designed computer programs, and observe the regulation and change of the result. Furthermore, we can find out when it will achieve the maximum.

本次試驗在設計一個氣壓式的夾娃娃機，首先運用課堂上所學習的氣壓實習與機電整合實習來規劃氣壓與電控部分部分，再利用機械原理與電腦輔助製圖來進行機械部分的設計，先把氣壓缸、氣壓夾爪與鋁擠型等元件3D 電腦化，利用3D 電腦影像來進行設計，可以讓我們更容易的掌控機具的比例，對初次設計機構的我們有很大的幫助。設計完成之後，我們也希望可以控制娃娃機的夾持的成功率，所以，設計了兩種方式來作為控制策略，首先以節流閥來控制氣壓的通過速度，結果發現，節流閥只能控制氣壓缸的出缸速度，並不能控制最後的夾持力量；第二種控制策略，利用PLC(可程式控制器)的程式來控制，結果發現，我們確實可以利用程式來控制，氣壓夾爪的點放時間和點放的次數，成功率都能夠依照我們的規劃來進行，是個又簡單又穩定的控制方式。

一般學生對於學校課程學習的負擔，再加上對本身的自信心不足，往往導致學生自己所「背」的東西不是十分確信是否有真正記進腦中，也常常困擾著他們。因此，引發本小組想設計一個可以自我評測且可以立即得到成績的輔助學習機;在研究過程中，本小組設計記憶學習機不但可以做到使用者自我評測的功能，還可以讓使用者馬上得到檢測的結果並且使用者可以回顧先前成績欄紀錄;記憶學習機經過本小組組員的辛苦孕育下誕生，本小組便拿著「它」讓班上同學認識，雖然「它」不是同學心中的最佳主角，但是同學卻一致認定「它」是『最佳伴讀夥伴』。本作品主要功能有:1．能調整使用者所要求的測試時問。2．該作品能記憶此次測試成績，以便和下次相互比較。3．依使用者的需求選擇中文、英文、數字及遊戲模式做記憶訓練。4．能有立即性的成效及回饋。 Due to the pressure of courses and lack of confidence, many students are often not sure of what they have recited on a lesson previously, which in turn always disturbs and cut down learning confidence of students. To eradicate the obstacles they encounter, we decide to research into this topic. A memory-based learning-aided machine is designed for students to self-evaluate themselves and to get the feedback at once. In the process of development, the memory-based learning-aided machine not only lets users practice the exercise of their own, but also is able to derive the outcomes immediately and retrieve the previous records effectively and efficiently. We strive to make this learning-aided machine at its best performance as possible as we can. Besides, the memory-based learning-aided machine provides the alternatives for the users to answer the question in a way that they like. For example, users can answer questions in English mode, can choose the limit time into test themselves in a time. In addition, the system can expand its material by inputting data into the knowledge base. By our group members' lasting efforts, the learning-aided machine was created, finally. According to the result of experiment that we applied to the classmates, we conclude that the memory-based learning-aided machine is the best assistant and learning partner for the students. We would like to introduce it to classmates and hope they will be interested in using it to enhance their learning motivation and performance.

1. Purpose of the research\r Nowadays, many encryption software are available to computer user. However, very few people use them which result in many cases of information and data leakage due mainly over the Internet. Most people use USB Flash Drive to store and carry confident files back home to work on. When the USB Drive is lost, the files stored are often leaked. To prevent this type of incident occurring, “CryptoDefender” is developed to enhance files protection and to change user’s habit in handling confidential information. \r 2. Procedures\r “CryptoDefender” is an add-in for common application software, e.g. Word, Excel, etc. It will appear as a new tab in the ribbon which provides the software an alternative for saving and opening a file. It protects the files in two ways: encryption and steganography. The data is first encrypted into cipher text as these encrypted data will be hidden in an image file to lower suspicion of readers. All of these procedures will be done by one click. For encrypt and decrypt, the user just needs to click the “Protect” and “Decrypt”. An extremely fast way to encrypt the file is “Quick Protect”. It will randomly choose an image from the image folder according to their file size. This function saves the time for choosing an image.\r 3. Data\r The method for steganography is using last two bit of R, last three bit of G and B to store the encrypted data. In 24-bit bitmap, RGB is represented the color of each pixel and each of them is 8-bit. The leftmost bit of each byte contains the highest value, and the right one contains the lowest value. Therefore, any change in the rightmost byte will only cause a minimal change in a byte value, and the color as well. 2-3-3 method is adopted to replace the pixels as encrypted data. It is used because it is in coordination with the program’s fluency. 2-3-3 is obtained so that 1 pixel will contain 1 byte of encrypted data. For R, the last two bit will be replaced by encrypted data. For G and B, the last 3 bit will be replaced by encrypted data. If the Bitmap size is larger than the encrypted data, random data will be replaced into the remaining pixels.\r 4. Conclusion \r “CryptoDefender” is user-friendly and efficient way to protect important and confidential digital files on most personal computers. This software will help to change the user’s habit in securing their information as to avoid data leakage even when they are accidentally lost.
